SPECIFICATION forming part of Letters Patent No. 503,616, dated August22, 1893.

Application tiled July 3Q, 1892. Serial No. 441,755. (No model.)

residing at Sparrows Point, in the county of Baltimore, State ofMaryland, citizens of the United States, have invented certain new anduseful Improvements in Ro1ling-Machines; and we do declare the followingto be a full,

ro clear, and exact description of the invention,

such as will enable others skilled in to make and use the same.

Figure l represents a plan view and partial horizontal section of amachine to which we haveapplied ourimprovements. Fig.2isaside elevationof a machine embodying our invention. Fig. 3 is an end elevationof oneof the standards or housings of our machine. Fig. 4: is an end elevationof one form of housing the art zo or standards which are also used inthe ma-V chine.

Our invention is primarily intended forA the- 3oV work of thatcharacter.

Our invention consists, with the above objects in view, in the followingconstruction and combination of the partswhich will rst be fully setforth and described in detail, and the features of novelty then pointedout in the claims.

In the following description We shall refer to the product of themachine, or the material which it fashions, for the sake of brevity, asan axle it being understood that that word is an equivalent to anyforging of which the machine is capable, as above indicated.

In the drawings-A represents the foundation bed of the machine.

B are the bed-tracks' upon which the housings are adjusted, bolted tothe foundation in any suitable manner.

C are the outer or end housings of the double set of rolls, and D, theinner housings of 5 0 the same. The outer housings are shown moreparticularly in Fig. 3, and the inner housings firmly thereon.

in Fig. 4. The outer housings C are arranged so that the axle may beinserted or withdrawn endwise through the saine. The inner housings Dare opened on one side, at E, so that `the axle may beinserted andwithdrawn when desired through the housings. The housings O D areprovided with rods or bars F which areA screw-threaded and have alsonuts, by means of which each of the housings may be independentlyadjusted sidewise along the tracks B.

VGr are bolts having hooked lower ends which engage the tracks B andhold the housings Two sets of rolls triangularly arranged, three in eachset, are preferably usedfor forging the bearings or seats for the vaxles.

H are the two lower sets of rolls mounted in bearings I, carried by thehousings C and D. .lare bolts by means of which an endwise adjustment'of the rolls H is secured, and K arebolts for adjusting saidrolls sidewise, or to and from each other.

Lis the top, roll in each set. These rolls are carriedin bearings Mwhich have vertical movements in suitable guideways in the housings Cand D. N are bolts by means of which an endwise adjustment of the rollsL may be had in the bearings M.

To secure the free vertical adjustment to the top rolls L the followingmechanism is preferably used: O are screws working 1n suitable bearingsin the top of the housings C and D, and connected to the bearingsMineach housing.` 1P. is a bevel-gear keyed to the screw O so as to turntherewith. Q is a shaft at right angles to the screws O and extendingacross the top thereof above the bevel-gears P. R is a series of bevelpinions which mesh with the gear P of all the screws O, whereby bothrolls L may be simultaneously adjusted vertically. This adjustment ofthe rolls L may be effected by hand by means of the large wheel S, or bypower, by means of the fast and loose pulleys T, or other known means.The rolls are driven bymeans of the pinion gear U and shaft V, carriedby suit" able bearings not shown, which mesh with the gear W keyed tothe long shaft X which extends through all the housings of the machine.On the opposite ends of shaft X are IOO keyed gears Y which meshwithgears Z, the

latter being splined to the shafts of the rolls H. A rotary motion iscommunicated to the upperrolls L through the medium of the axle 2, whenthe rolls L are let down in `contact therewith. Where the axle 2 isinserted and are pivoted at their upper ends, at 4, to the bearings M,in the housings D, s o as to have an up and down movement in connectionwith said bearings. 5 are rolls having bearings in and forming thebottom of the stir rups 3. l v j When it'is desired to -insert anaxle'into the machine for rolling the seats or bearings,`

the shaft Q is rotated so as to lift the -rolls L thereby carryingupwardly the rolls 5 on the stirru ps 3. The axle is then insertedendwiser` by beingrolled upon and supported by the stirrup-rolls 5. Whenthe axle is in position the shaft Q is again rotated so as to lower therolls 5 and the rolls L, so that the axle 2 will rest upon thelowerrolls H, the rolls 5 passing below and out of contact with the axle 2.When the axle is finished the reverse Inovement of the rolls L and 5takes place, the latter coming in contact with the axle and raisingitfrom contact with the rolls H so that it may be withdrawn endwise fromthe rolls 5. When it is desired to insert and remove the axle sidewiseto and from the machine, the following mechanism is employed: 7 is atrack or way for supporting the axle in its treatment by the machine. 6is an extension of the way or track which is pivoted at its outer endand its inner end carried and supported by'a link. 8 which is pivotallyconnected to the track 7 at its lower end and to the bearings M at itsupper end, by a pivot 9.

In Fig. 4 the axle 2 is shown being rolled by the rolls L and H. Whenthe axle is finished and it is desired to remove the same the shaft Q isrotated so as to raise the rolls L and the bearings M, which causesthelink 8 to move upward, raising the track 7, thereby engaging the axle2 and raising it as the rolls L move upward until the angle is such, asshown in dotted lines, that the axle may be rolled downward and outwardfrom the machine onto the track or support 6. verse movement takes placewhen the unfinished axle is placed in the machine for finishing orforging.

We have termed' our invention a multiple rolling machine as beingpeculiarly appropriate to the work which it is chiefly designed toperform. We may roll more than one axle at the same time-by increasingthe length of vthe machine and providing additional sets of rolls forthat purpose. All the features of our invention however which aregermane toV one set of rolls we desire to claim in connection therewith,and also in addition, to claim the same in connection with two or moresets of rolls.

We intend using this machine in connec- Are@ sos,e1e i tion with-animproved composite axlemade from a sectional pile, for which wehavereceived Letters Patent. We purpose rolling the wheel-seats or journalsof the car-axles, either hot or cold. By vmeans of this manipulation androlling we dispensel with the ne cessity, andthe consequent cost, ofVturning the wheel-seats and journals. At the same time we obtain allthe advantages of coldrolled iron or steel, both in strength and wearingproperties. The rolls H and L are turned to any shape required accordingto the work performed. The gear-wheels Y are adjustable longitudinallyupon the shaft X in order to Vpermit the adjustment of the housings Cand D. We roll the wheel-seats and journals on both ends of'a car-axleat the same time, and without the rolls comingin contact made, besidesturning out a larger output vfrom a given outlay in the plant.

There are various methods in which our machine may be modified-in itsstructure and still come within the scope of our invention.

i These structural changes will suggest` themselves to any mechanicskilled in the art. Our invention. is designed to cover such obviouschanges. v

We claim- 1. The combination of two sets of rolls arranged in an axialline lwith each other and 'separated so as to leave a clear spacebetween the sets of rolls, housings for the same, bearings carried inthe housings, mechanism for adjusting both of the lower setsof rolls inythe line of their length, mechanism for adjusting both of the lowersets of rolls laterally or transversely, and mechanism for adjusting thetop rollof each set of rolls vertically. j

a set of rolls carried in each housing, adj ust--` able bearings in saidhousings for the upper roll, and forging-supports carried by said upperroll so as to move therewith.

' 6. The combination of two separate sets of rolls, housings for thesame, adjustable bearings in the housings for the top rolls of the sets,and forgingsupports carried thereby, adjusting screws for said bearings,and gearconnections for the screws whereby said bearings aresimultaneously adjusted.

7. A set of rolls triangularly disposed, mechanism for verticallyadjusting the top roll, mechanism for adj nsting each of the lower rollsin the line of its length, and mechanism for laterally or horizontallyadjusting each of the lower rolls.

S. The combination of a set of rolls, housings for the same, means forvertically moving the top roll or rolls, a track or way pivoted at oneend and connected to the vertically moving roll or rolls at the other,whereby the inner end of the way or track is moved up and down inconnection with the top roll or rolls.

9. The combination of two or more housings having beariiigs for one ormore .sets ef rolls of three rolls each, journal-bearings in thehousings for the two lower rolls of each set, means for laterally andlongitudinally adjusting said joiirnal-bearingsin the housingsindependently of one another, a vertically moving bearing for the toproll of each set, means for laterally and simultaneously adjusting eachof said top rolls, and means for driving said rolls.

lO. The combination of a set of rolls, housings for the same, means forvertically moving the top roll or rolls, and a stirrup support connectedto and moving up and down with the top roll or rolls, whereby theforging may be fed axially and longitudinally into the rolling machine,adj ustably supported therein by said stiri'up support or supports andsimilarly removed therefrom axially or longitudinally.
